40s to 50s from napa to santa rosa. san jose, 53. our coast is cool at 50 degrees. a couple of things going on. this morning we are starting out cooler but by the time we hit or afternoon highs, 3:00, 4:00, we will be the same as we were yesterday. very little change over the next couple of days. there is a good reason for that. there is a system offshore that is diffuse that go marine layer, allowing for a sun cloud mix throughout the rest of the weekend. it will head our way bringing a slight chance of showers. an upper-level low, it remains blocked, it can't move close to the coast but it will continue total flow total south and west of us to bring us high and mid-level clouds. here is track of it throughout the rest of the weekend. staying offshore. that is provides a partly cloudy sky. then as we head towards the beginning of the workweek, monday and tuesday it sinks south. higher elt vacation sprinkles perhaps. east bay hills, santa cruz mountains and dusting of snow in the sierra nevada. cold enough and been in the lower 30s this morning. mid 60s in the northern sierra.
